The three-time Oscar winner donned the Republican nominee’s signature coif, a fat suit, an extra-long red tie and orange makeup to perform a rendition of Cole Porter’s “Brush Up Your Shakespeare” at the Public Theater Gala in Central Park.

The legendary 66-year-old actress sang a few show tunes with Tony winner Christine Baranski for the annual event that honors the Bard.

“You’ll let me know, why all the women say no,” Streep crooned from “Kiss Me, Kate,” which is based on “The Taming of the Shrew.”

“Brush up your Shakespeare and the women you will wow,” Baranski sang back.

Streep is a long-time Hillary Clinton supporter — and the feeling is mutual.

Clinton said in 2014 that she’d choose Streep to portray her in a movie.
